Some questions intended to help. Please feel free to ignore them.

Would this bug manafest itself if a member were to login in from several machines and never logout from any of them?

I guess I'm asking if the bbs needs the user to logout of a session on one computer before logging in on another?

Does the logout cause the server to read the final state of the cookies, so that information is available to be dumped into the next browser session?

I ask these questions because earlier it was said that the server stores some state information in cookies on the local machine.

Also would the borwser preference about checking the copy that is in cache, against the network version, have an impact on what the user sees happening?
